51822 adverting again and again, stop in somewhere

Bruce

Hi experts,

 i found one issue that if i continue to make the 51822 advertise(if advertise timeout, start again), sometimes the 51822 will stop in somewhere. I'm sure that it is not reset. After several seconds later, it  worked well. The issue trouble me for several weeks. The softdevice and the sdk are latest. There are several 32hz interrupt events need to process when advertising. May be caused by these events?

    Which version of the softdevice are you using? With versions 5.2.0 there was an issue which could cause advertisements to stall under certain environmental conditions, but this has been fixed in version 5.2.1. I'd therefore recommend you to retry this with 5.2.1, and see if this fixes the problem.

    If this does not help, could you please share your application, so that I can test it here? Giving a little more details on what behavior you see and what you expect would also be helpful. If you can't share your code openly, you should consider opening a support case and upload your code there. Everything posted in a support case is treated in confidentiality.

    Hi Ole, I'm sorry that I reply so late.My softdevice version is 6.0.1. I have remove other module in my project, only ble module and timer app module existed. This phenomenon appears less than before, but still existed. When the board start to advertising, there are 5 pieces of LED turn on. May be caused by the supply of current ?

    If the input voltage drops below 1.9 V, there could very well be problems, yes. Also, if you draw more than 15 mA through the GPIOs, this may also cause trouble.

    However, I'd also recommend you to try using version 5.2.1 of the softdevice, since the only version 6.0.0 that is yet available is still an early alpha.
